Apple has reportedly begun seeding iOS 7.0.3 to some of its own employees and carrier partners

From MacRumors:

According to our sources, Apple has seeded iOS 7.0.3 to employees and partners for final testing. We?re not sure exactly when the new software will be released to the public, but we believe it will be sometime next week. The build number of iOS 7.0.3 is 11B491.The claimed build number appears to be somewhat at odds with Apple's usual numbering patterns over the past several years, which should see all iOS 7.0.x releases carrying 11Axxx build numbers before moving on to 11Bxxx builds for iOS 7.1.x.
